The case was heard at Craigavon Magistrates' Court.
Pre-sentence reports are to be prepared after two high-value shoplifting thefts on the same day were accepted.
Julie Mary Larkin (43) from Garvaghy Road, Portadown admitted stealing household items totalling £263 from Tesco, Craigavon on 19 August 2021.
On the same day she stole £536.22 of similar items from The Range, Portadown.
A defence lawyer told Craigavon Magistrates Court a pre-sentence report would be helpful and District Judge Bernie Kelly agreed, particularly given the sums of money involved.
Larkin was ordered to return for sentencing on 22 June.
